Sc: application advantages of LED electronic display screen
LED electronic display screen is from tens to hundreds of thousands of semiconductor light-emitting diodes figure yuan points equally arranged.
Use different material can make different color LED pixel figure.
Destroy by lamp light to display characters.
Used to display text, graphics, images, animation, quotation, video, video signal display weaving of various kinds of information.
Not only can be used in indoor environment also can be used in outdoor environment, with a projector, TV wall, LCD display screen the incomparable advantages.
LED is widely attention and got rapid development, with it itself has the advantages of the inseparable.
These advantages in summary is: 1, high update (
In the frame)
Not less than 300 hz)
Greatly improve the stability of the image.
2, high gray scale (
Makes the conventional RGB image data eight bits (
The class of 256)
Extension is 14 yuan, respectively, and through the way of local control scanning, converts, 14 yuan data completely 214 = 16384 brightness level, so as to realize gray level 16384.
3, borrow by human eyes visual characteristics, according to the change of the ambient light during the day and night, high brightness and low brightness values change (
According to the color look-up table)
LED electronic display screen.
The combination of 4, reasonable structure, simple, to display the weight to a minimum.
5, reasonable working current, neither reduce brightness, and improve the working efficiency.
6, adopts data partition processing, each piece of synchronous parallel communication way, greatly improves the speed of the communication.
7, adopting photoelectric isolation technology, greatly improve the antistatic performance of the lightning protection.
LED electronic display screen can be remote control system on the Internet.
